Automatic charging apparatus for tracking robot

The invention discloses an automatic charging apparatus for a tracking robot. The automatic charging apparatus comprises a plug which is installed at the bottom of the robot and a socket which is installed on the floor; the plug consists of a push-rod motor, a plug main body and a framework; the bottom of the plug main body is provided with two pieces of electrodes, and the front end of the plug main body is provided with a conical lead-in oblique surface, and the conical lead-in oblique surface is driven by the push-rod motor to move up and down; the socket comprises a base which is fixed on a floor magnetic rail, a guide rail and a U-shaped guide plate; the U-shaped guide plate is connected with the guide rail by virtue of a spring on the bottom. The positioning of the plug and the socket in the left-right direction is realized by virtue of the guidance of the oblique surface part of the plug and a U-shaped opening of the socket, and the precise positioning of the plug and the socket in the front-rear direction is realized by virtue of a fourth limiting switch. A transverse guide rail is designed on the bottom of the socket, so that the socket can slide from left to right, and when the plug and the socket are deviated in the left-right direction, the U-shaped guide plate can be communicated with a jack to slide laterally along with the deviation of the robot, so that the positioning in the left-right direction is completed.
